You're not properly grounded. Double check the ground at the switch and the box to the panel.

Mine only hums if the water is low. Otherwise it is virtually quiet. Make sure it is filled to nearly the top. If that doesn't help maybe the motor is bad.

I not totally sure, but I know if there is humming you have some electrical interference. The cables are possibly too close to the conduit in the walls or some other issue. I've had no problems with my setup, but when I turn my microwave on the sub hums. Not a big deal for me since it's not used much. So it's worth a try, if not return it.

My unit does not make a loud buzzing sound but does have a slight humming sound from fan operating similar to a computer. Call tech support, they are awesome

I have several of the units and there is not a buzz noise only a hmmmm like a fan. I think something must be lose in your unit. I can put mine on silent and I don't hear it at all...try that....if its still buzzing then something is wrong. They are great units.

It is a low pitch hum. Usually mine is on low and I get used to it and don't really notice it. Higher speed is more noticeable, but still more a medium pitch, not high-pitched.

I just started to notice that mine also makes the little humming sound. Kinda annoying

Yeh, I bought mine 10/15/08 and had the same problem.It turned out to be a ground loop between my Receiver and my Samsung TV.I put a two-prong "cheater" on the Samsung power plug and that fixed it.Not the best way, but the hum is gone.

Mine does the same thing but I don't often notice it. Mayby a move to another area or chose a different speed setting. I leave mine on auto and moved it to a corner of the room and that solved the hum/whine issue.

it will make a slight hum but if its that noisy take it apart and clean and reassemble may help

As Jeffrey...Yes, I have the same hissing sound on my unit too... I am from Canada, and I cannot shipping it back to the USA since It will be too expensive to do so, so I'll just keep it as is.

I have not had that problem. It sounds like a bad power switch or loose connection on the power supply. I would return it and get a replacement if you can. Mine has worked great for several hours of use so far.

Our ballast does gives off humming sounds. But on the older ballast gives off buzzing sounds. So to answer your questions, yes, it is very annoying.....

Have you tried switching your cable? I've never gotten any humming when playing this, either through a tube or solid state amp.

Yes Amy, the unit makes a low humming sound with a slight vibration when in use. Make sure you use a little bit of liquid soap or jewelry cleaner in with the water.

I have not had that problem, love mine, sorry I was not any help, sounds like a defect or an impedance problem to me.

I had the same noise with mine. Couldn't figure out why. It stopped when I upgraded to the Nest Thermostat.
